Subject: Configure: fix pkg-config paths for absolute build directories
X-Git-Url: https://git.kaiwu.me/?a=commitdiff_plain;h=8e9a4663dcfda31ace7fc6014d36267a7def9e09;p=njs.git

Configure: fix pkg-config paths for absolute build directories

The generated njs.pc prepends the source directory to an absolute
build directory, producing invalid include and library paths.

Preserve absolute build paths and resolve only relative ones against
the source directory.  This also supports engine builds embedded in
nginx without changing the standalone CLI configuration.
